Yeah, MS pages....
I did the same thing back in November, when I was finishing off the last few chapters of KINGS. We were doing NaNoWriMo, and so I didn't post my full wordcount on that day. Didn't want to look TOO arrogant.
(I did 1,500 words! I did 2,800! Uh, I did 16,000....)
Like I said, when I get near the end of a book, I just go. Everything's generally in place plot-wise and image-wise. I usually plan the endings of my books from the start, and they're among the most well-conceived visually. When I get there, it's just a matter of putting the words on the page.
And yes, I'm very happy with this book. Of course, I've been happy with books before that people haven't liked as much as some of my others. However, I think MBFE is a very strong, 'classic' Brandon novel, in the style of ELANTRIS and WHITE SAND. I think people will enjoy it. I'm eager to finish the ELANTRIS rewrite (about 10% done right now) so I can move on to cleaning up MBFE so I can print/mail off review copies to people.
